Title: Magnetic head
Inventor: MATSUYAMA HIDEAKI
IPC: C04B37/00
Filed: 1988-08-29
Abstract: PURPOSE:To reduce waviness on a junction interface due to the growth of monocrystal ferrite by interposing an intermediate layer on the junction interface of the monocrystal ferrite with polycrystal ferrite. CONSTITUTION:A monocrystal ferrite part 1 on the sliding plane side of a magnetic recording medium and a polycrystal ferrite part 2 on a back gap side are joined and unified via the intermediate layer 3 of oxide magnetic thin film. The intermediate layer 3 regulates the maximum value of the waviness of solid phase diffusion to a range of sliding noise level which causes no problem in practical use i.e. between 10mum and 30mum, not cutting off the solid phase diffusion of the monocrystal ferrite completely on the junction interface, and gives joint strength with high reliability. Thereby, it is possible to obtain a magnetic head with high yield and high reliability.
